Yeah, I love it too.
It is so funny when I meet a non-meta deck. Those decks are so funny and easy to crush when you follow the meta guides as everyone should.
The others refuse to pay to blend in the meta. It feels so good to make them regret not paying cash to use meta decks.
I like playing one-sided games with the power of money while watching the free-to-play non-meta decks struggle.
To have all the cards you need for a good deck you will have to farm a long time. Meaning you have less time for anything else. I'm not sure that is better than simply paying with cash.
You also take more time to build new meta deck whenever new boxes are released for purchase.
You played this game for a long time, so you can afford being F2P more easily than beginners who have 0 gems and tickets
